Quinolone Resistance Reversion by Targeting the SOS Response

mBio, 2017
Suppression of the SOS response has been postulated as a therapeutic strategy for potentiating antimicrobial agents. We aimed to evaluate the impact of its suppression on reversing resistance using a model of isogenic strains of Escherichia coli ...

Hypersensitivity reactions to quinolones

Current Opinion in Allergy & Clinical Immunology, 2011
The purpose of this review is to examine in detail the new advances in the pathomechanisms and diagnosis of immediate and nonimmediate hypersensitivity reactions to quinolones, as well as analyze cross-reactivity among different quinolones.Hypersensitivity reactions to quinolones, especially anaphylactic reactions, have become more common in the past ...

Investigation of the Coordination Chemistry, Biomolecular Interactions, and Cytotoxicity of Heterocyclic Carboxamide Manganese(II) Complexes

European Journal of Inorganic Chemistry, EarlyView.
Mononuclear and dinuclear heterocylic carboxamide manganese(II) complexes show strong interactions with calf thymus DNA and bovine serum albumin biomolecules but low cytotoxicity against Caco‐2 and MCF‐7 cancer cell lines and relatively less selective toward the normal KMST‐6 cell line.

Comparative Genome Analyses of Wild Type- and Quinolone Resistant Escherichia coli Indicate Dissemination of QREC in the Norwegian Broiler Breeding Pyramid

Frontiers in Microbiology, 2020
Quinolones are important antimicrobials for both humans and animals, and resistance toward these compounds is a serious threat to public health. In Norway, quinolone resistant E.

Effect of pH on ciprofloxacin ozonation in hospital WWTP effluent [PDF]

, 2009
A bubble column was used for ozonation of the quinolone antibiotic ciprofloxacin and the effect of pH was tested. Degradation at pH 7 increased the ciprofloxacin half life time to 29.1 min compared to pH 3 (26.8 min) and pH 10 (18.7 min), possibly due to

Analysis for prevalence and physical linkages amongst integrons, ISEcp1, ISCR1, Tn21 and Tn7 encountered in Escherichia coli strains from hospitalized and non-hospitalized patients in Kenya during a 19-year period (1992-2011) [PDF]

, 2013
Background: We determined the prevalence and evidence for physical linkage amongst integrons, insertion sequences, Tn21 and Tn7 transposons in a collection of 1327 E. coli obtained over a 19-year period from patients in Kenya.

The small quinolone derived compound HT61 enhances the effect of tobramycin against Pseudomonas aeruginosa in vitro and in vivo. [PDF]

, 2020
HT61 is a small quinolone-derived compound previously demonstrated to exhibit bactericidal activity against gram-positive bacteria including methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). When

Enantioselective Anion‐Binding‐Catalyzed Nucleophilic Addition to 4‐Quinolones

European Journal of Organic Chemistry, EarlyView.
The first organocatalytic enantioselective formal 1,4‐addition to 4‐quinolones has been developed. This method relies on chiral triazole‐based anion‐binding catalysis using enol nucleophiles, complementing previous metal catalytic approaches. Moderate to good yields and enantioselectivities were achieved by in situ silylation and formation of a key ...
